I believe that there is a slight global warming, but I think this is just part of the natural cycle of things. The earth has warmed and cooled many times over the years. Look at Greenland, named because when discovered by Eric The Red it had extensive lush green grasslands, which disappeared as the climate changed. Also the notion that the ice caps are melting has been contradicted by many scientists who say that although the coastal ice of Greenland is depleting the actual ice core is thickening because of more snow falling inland.

I think the attitude that man is the cause of global warming is arrogant. Much more greenhouse gasses are released in a single volcanic explosion than man produces. While manmade pollution may be a contributing factor in global warming, I think it is a miniscule one.
Jam it back in, in the dark.
